We've all been taught how to write a 5 paragraph essay, but we need to revisit exactly why it is such a strong writing and speaking tool:
This outline for a 5 paragraph essay does not leave one subject to uphold the argument, and absolutely no subject is alone. There are always at least two categories per idea, supporting evidence, and details or examples. These subjects interact with one another in order to form a stronger argument.
This outline also allows paragraphs to flow easily between subjects. Following the example outline above, you should have a speech paragraph that is structured like this:
Topic sentence. Main idea. Support/evidence. Detail/Example. Detail Example. Concluding Sentence. Transition sentence.
Your speech paragraph should always begin with your observations and/or ideas, and it should always end with a transition sentence that transitions into your next topic sentence. The transition sentence connects your ideas and introduces the next point of your speech.
